Hi Gareth. What a beautiful rottie in your status pic. Very important to sort this problem out... your pooches MUST be walked everyday for at least an hour. I would even suggest a walk in the morning and a walk in the evening, if you are unable to do it, maybe someone else can help you. When dogs are bored they bark, chew, dig, or in worse cases, are aggressive. If this does not help the problem please let me know, and try and keep me updated.
